Android Basic 4.x: Photon works!?!?

Hello everybody.
I am in the midst of writing a book on multiplayer in Unity. I have come to a chapter on Photon Unity Networking w/ Photon Cloud.
Purely for kicks and grins, I decided to push a demo scene to an Android device with my Android Basic license, fully expecting it to fail.
To my surprise, it successfully connect to Photon.
"Wait, what?" I thought to myself. Doesn't Android Basic restrict .NET sockets? And surely Photon uses them? I know for a fact it does. So why does it work?
I knew this issue existed under 3.x, but I swear I saw a release note saying they fixed that.

I do have a Unity Pro trial, but this does not appear to affect my Android builds: in all other respects, I appear to have a plain old Android Basic license (for example, image effects do not work).

So what's going on here?

 

BUMP

I normally wouldn't bump so quickly, but I would love to have this answered ASAP.

If this is induced somehow by having a Pro trial active, then OK, I'll continue to use Unity Networking for my personal projects.
However, if this is a bug in the current version of Unity..... is there anything wrong with me taking advantage of the bug? (I'm not kidding, if I can use Photon without having to get my hands on $3,000 just for the one feature of .NET sockets, I definitely will. It's far superior to Unity Networking - no offense, UT)

 

I am monitoring this thread!

 

In case anybody is reading, I have just discovered the answer.

This is indeed a bug in Unity caused by having a Pro trial license (unless this is intended behavior?? I doubt it)
After my Pro trial expired, the APK would no longer compile due to referencing System.Net.Sockets.
